Abstract:This study was carried out as part of the BALANCE bus-priority-system evaluation. The objective of this study was to estimate the improvement in freeway passenger flow resulting from the reservation of priority lanes for buses and carpools. These estimates are based on the given conditions of the freeway before reservation, including observed speed-flow characteristics, auto- and bus-flow rates, auto-occupancy characteristics, bus-to-auto ratio, and total number of freeway lanes in one direction. The numerical results show the effects of the policy variables (number oflanes reserved and minimum carpool occupancy) on the passenger flow. An appendix includes an improved mathematical expression for the empirical speed-flow relationship.
